Polly is a powerful being now, far too powerful for a thirteen-year-old girl. She has learned that "things" that go "bump" in the night are not always tree limbs blowing against the side of a house. In Comes a Gathering, book 3 of the series, Polly finds one vampire is bad enough, but a gathering is a family of vampires! She wields a power she can barely comprehend and has been charged by those as do mentor her, "Do not engage violent adults, you are too young, in here"-a finger gently indicates her chest above her heart-"and in here"-that self-same finger gently touches her forehead. So it is that the Mistress of the Night, who is instructing her, cautions her.
